This invention relates to a bulb manipulating device and especially to a device such as is particularly intended for attaching or extracting.

electric light bulbs from sockets in high or remote positions.

This invention is particularly adapted for use in connection with a bulb manipulating tool such as covered by my Patent No. 2,117,017, issued May 10, 1938, Tools for manipulating electric lamp bulbs.

An object of the present invention is to provide a device for use with the said tool to permit the manipulation of electric light bulbs that may be contained in sockets that are disposed in different positions and at different angles.

A further object is to provide such a device which can be quickly and easily adjusted to position the bulb engaging member at difierent angles and to rotate the same while in said positions.

Further objects and advantages of my invention will be more clearly understood from the following description and from the accompanying drawings in which:

Fig. 1 is an elevational side view of a device embodying my invention.

Fig. 2 is a fragmental side view, partly in central vertical section, showin the device adjusted for a difierent position.

Fig. 3 is a similar view showing the device adjusted for another different position.

Fig. 4 is an elevational plan view of the device as shown in Fig. 3.

Fig. 5 is an elevational plan view of the adjustable supporting member used in my device.

Fig. 6 is an elevational side view thereof.

As shown in the drawings, the numeral 5 denotes a sleeve or shell which is adapted to be mounted upon the end of a pole to permit reach ing of bulbs in high positions. Upon the top of said shell, there is secured a ring gear 6 having a row of gear teeth 1 and a plurality of teeth or projections 8 for the purpose to be hereinafter described.

A supporting member 9 is slidably mounted within the sleeve 5 and through the gear ring 6, and a post In is swivelly secured to said member by means of a pivot pin II. The said post being permitted to swing within a notch 12 in the end of said supporting member 9 and the opposite walls Of said notch being provided with oppositely disposed recesses l3, l4 and [5 to provide sockets for a hub It on a, pinion I! which is rotatably mounted on the post Ill. The said pinion having a row of teeth I8 adapted to mesh with the teeth 1 at different angles relatively thereto for rotat- 6 Claims. (Cl. 294-21) ing a shank H! which is secured to said pinion by means of a sleeve 20 providing a socket for said shank.

The said pinion is rotatably secured to the post it by means of a screw 2| having a tip fitting within an angular groove 22 in said post and the supporting member 9 is adjustably secured to the sleeve 5 by means of a spring operated positioning pin 23 which is normally urged into one of a series of positioning recesses 24 in said supporting member 9 for rotatably securing the member at different positions relatively to the shell 5.

In the operation of my invention, the shell 5 may be secured to the top of a suitable pole or bar which will reach the position of the bulb to be manipulated.

When it is desired to remove an electric light bulb from a socket in a high position, the bulb gripping member 25 may be placed at the proper angle, corresponding with the position of the bulb, by first loosening the screw 2| to permit raising of the pinion I! on the post I0 so as to remove the hub l6 from the recesses in the sides of the slot l2 within which it is positioned. The member 9 is released, by pulling on the handle 26 to removethe pin 23 from the recess 24, and the member 9 may then be pulled upwardly in the shell 5 to permit the post H] to be tilted to the angle desired and the hub l5 inserted into the corresponding recess in the sides of the slot l2. The screw 2| is then brought into positioning engagement with the groove 22, the member 9 slid downwardly to bring the teeth of the pinion l1 into engagement with the teeth 1, and the spring pin 23 is permitted to enter the recess registering therewith to secure the said member in position.

After the device has been adjusted for the proper angle in the manner above described, it may be raised to permit engagement of the gripping member 25 with the bulb and the bulb may then be rotated in its socket by simply rotating the pole. This will in turn rotate the sleeve 5 and the gear 6 will rotate the pinion I! on the post l0 and thus rotate the member 25 to either screw the bulb into the socket or unscrew the same from said socket.

It will be noted that the hub l6, fitting within the recesses in the edges of the slot I2, will position the holder l9 at the proper angle and permit rotation thereof with said hub rotating within the recesses; moreover positioning of the member 9 by the spring held pin 23 will retain the pinion in mesh with the ring gear 6.

It will also be noted that the angle of the shank 9 may quickly be changed by simple manipulation of the screw 2| and the pin 23. As it will be seen from the drawings, the shank I9 may, relatively to the pole, be positioned diagonally, as shownin .Fig. .2, by inserting the hub 16 in the recess l5. It may be positioned perpendicularly, as shown in Fig. 1, by inserting the said hub in the recess I4, or it may be positioned straight with the pole, as shown in Fig. 3, by inserting the hub in the recess l3. When in this straight-position, the teeth I8 on the pinion H will be in engagement with the teeth 8 and thereby preventro'tation of the pinion and shanklQrelatively to the support 9 and shell 6 so that'thesaidshank may be rotated directly with the support andthe pole connected thereto.

The gripper 25 may be reversed upon the shank It to permit use of the tapered end 2'! when needed for such as the extraction ofitheshell of a broken bulb.
